Hello! First time forum poster here looking for some assistance with the request module in SD+. I'm running v14300 and one of my technician support groups has suddenly lost the ability to enter an owner on a worklog:

Other technicians in this support group cannot add an owner either, but their permissions give then the ability to manage everything in their own requests except for delete them. What would suddenly prevent this group from entering an owner and being able to close their requests? This seems like it should be an easy fix, but maybe I'm just overlooking something?
